PATH SELECTION STRATEGY UTILIZING TYPE OF SERVICE (TOS) IN SOFTWARE-DEFINED WIDE AREA NETWORK (SD-WAN)

Abstract: an sd-wan route is selected based on the tos parameters matching real-time sd-wan link quality requirement by matching jitter, latency and/or packet loss requirements of tos parameters to highest ranking links over a route. the tos parameters for a specific application can be parsed from data traffic and matched to optimal sd-wan routes. the data traffic of the first data packet and subsequent data packets of the first session is output to the selected sd-wan link.
